Description

Voice playing method and system supporting multiple currencies, SCP and IP

Technical Field

The invention relates to the technical field of intelligent networks, in particular to a voice playing method and system supporting multiple currencies, a Service Control Point (SCP) and an Intelligent Peripheral (IP).

Background

The intelligent network technology system mainly includes a Service Control Point (SCP), a Service Switching Point (SSP), an Intelligent Peripheral (IP), and other functional entities. The SCP is the core component of the intelligent network and stores subscriber data and service logic. The SCP has the main functions of starting different service logics according to the call events reported by the SSP and sending call control instructions to the corresponding SSP according to the service logics, thereby realizing various intelligent calls. SSP provides call connection function, SSP can detect intelligent call request and establish control relation with SCP; in response to the indication by the SCP, service logic in the SCP is allowed to affect call processing. IP is a special resource that assists in completing intelligent services, and generally has various voice functions, such as voice synthesis, playing recorded voice announcements, receiving dual tone multi-frequency dialing, performing voice recognition, and so on.

In the intelligent service, the SCP often interacts not only with the SSP, but also with the IP to implement the man-machine interaction between the service flow and the user, play a voice prompt to the user and collect user information, the IP may be integrated in the SSP or independent of the SSP, the SSP integrated with the IP is called an integrated SSP/IP, and the IP independent of the SSP and serving as a device alone is called an independent IP. The SCP firstly requests the SSP to connect the current call to the IP device, and then sends an instruction to the IP to request to play the notification sound or play the notification sound to the current calling party and collect the user information.

In the intelligent network service, the service interacts with the user through the IP equipment, plays notification sound to the user and collects user information. In the parameters of playing voice Prompt (PA), voice Prompt And collecting User Information (PC), voice Prompt And receiving variable Part (variable Part) in the operation of Message (PR), voice Prompt And receiving (PR), the definition of Price only defines the Price value field, And does not define the currency type corresponding to the Price. In the actual service operation process, different users of the same service may have accounts of different currencies, and since the definition of the variable part parameter for Price only defines a Price value field and does not define the currency type corresponding to Price, the IP system can only use one default currency to play the voice prompt, and cannot meet the actual operation requirement of the service.

Detailed Description

The invention is described in detail below with reference to the figures and the embodiments.

The first implementation mode comprises the following steps: setting currency type variable sound parameters, receiving a playback operation instruction from a Service Control Point (SCP) by an Intelligent Peripheral (IP), extracting currency type information and amount information from the playback operation instruction, carrying out voice synthesis, and playing an amount prompt sound containing the currency type.

Example one: an amount and currency type (priceandcurrenttype) field is newly added to include both variable amount information and currency type information.

The following description will take the INAP protocol and the CAP protocol as examples. In order to meet the requirement of multiple currencies in the actual operation process of the business, the variable part (variable part) parameter in the playback operation instruction needs to be modified and expanded on the basis of the original standard specification, and an amount and currency type (priceandcurrenttype) field is added, wherein the amount and currency type field comprises current currency type information and amount information. According to the actual operation requirement, the playback operation instruction comprises a Play audio Prompt (PA) operation, a PC (Prompt and select User Information) operation, or a PR (Prompt and receive Message) operation, or any combination of the three.

For the CAP protocol, the modification of the present embodiment to the standard is defined as:

VariablePart::＝CHOICE{

integer [0]Integer4，

number [1]Digits，--Generic digits

time [2]OCTET STRING(SIZE(2))，--HH:MM，BCD coded

date [3]OCTET STRING(SIZE(4))，--YYYYMMDD，BCD

coded

price [4]OCTET STRING(SIZE(4))

priceAndCurrencyType[31]OCTET STRING(SIZE(5))

}

the definition of PriceAndPrencyType is shown in Table 1:

TABLE 1

From the above description it can be seen that: under VariablePan, a priceAndCurrency type field is newly added, and the current currency type information and the amount information are contained in the field. If the SCP issues the priceandcurrenttype field to the IP, the IP can extract the currency type and amount information directly from the received message.

For the INAP protocol, the modifications are as follows:

VariablePart ::＝CHOICE{

integer [0]Integer4，

number [1]Digits， --Generic digits

time [2]OCTET STRING(SIZE(2))，--HH:MM，BCD coded

date [3]OCTET STRING(SIZE(3))，--YYMMDD，BCD coded

price [4]OCTET STRING(SIZE(4))，--BCD coded

priceAndCurrencyType[31]OCTET STRING(SIZE(5))

}

the definition for PriceAndPrencyType is shown in Table 2:

TABLE 2

Similar to the CAP protocol, under VariablePart, a priceandcurrenttype field is newly added, and the field contains the current currency type information and the amount information. If the SCP issues the priceandcurrenttype field to the IP, the IP can extract the currency type and amount information directly from the received message.

For the network intelligent network mobile application part (WIN MAP) protocol, the following is modified:

playback operation indicates that the bearer is operated due to dedicated resource function indication (SRFDIR). Since the SRFDIR operation includes two types of playback modes: one is a playback mode indicated by a voice list parameter (AnnouncementList), and the other is a playback mode defined by an execution script (ExecuteScript). Because the voice list mode can not support the variable voice playing, the script mode is adopted to play the variable voice. The ExecuteScript parameter definitions defined by the WIN MAP-related specification are shown in Table 3:

TABLE 3

The name of the script (script name) and the script execution control (script) parameter are not explicitly defined in the existing specification, but a maximum byte length of 96 bytes is given. Changing the value of script can change the played voice. Here, the format of the script arrangement defined in this example is shown in table 4:

TABLE 4

The format of the fixed part is shown in table 5:

TABLE 5

The PriceAndPrencyType field has been added, so there are 7 total voicing types:

number 1

Integer Integer 2

Date 3

Time Time 4

Amount Price 5

Duration 6

Money amount PriceAndCurrency type 254 containing currency

The definition of PriceAndPrencyType is shown in Table 6: when the money amount containing currency is played, the variable tone part is 9 octets.

TABLE 6

As can be seen from the above description, a changeable tone type, namely, priceandcurrentncytype field is newly added, and the field contains the current currency type information and amount information. If the SCP issues the priceandcurrenttype field to the IP, the IP can extract the currency type and amount information directly from the received message.

Example two: the existing amount parameter is modified to include both variable amount information and currency type information.

This may be accomplished by modifying some of the bit meanings of fields of the Price sub-parameter in the PA, VariablePart parameter in the PC operation defined by the INAP/CAP specification, or the Script sub-parameter in the WIN MAP specification defined SRFDIR operation ExecuteScript parameter.

For example, the variable part parameters defined by the CAP specification are as follows:

VariablePart::＝CHOICE{

integer [0]Integer4，

number [1]Digits，--Generic digits

time [2]OCTET STRING(SIZE(2))，--HH:MM，BCD coded

date [3]OCTET STRING(SIZE(4))，--YYYYMMDD，BCD coded

price [4]OCTET STRING(SIZE(4))

}

the structure of the existing price is shown in table 7:

TABLE 7

--bits	HGFE	DCBA
			--	tens of thousands	hundreds of thousands
--	Hundreds	thousands
			--	0～9	tens
--	Hundredths	tenths

Here, the E to H bits of the first byte of price may be used as the currency type. The modified price structure is shown in Table 8:

TABLE 8

--bits	HGFE	DCBA
			1	Currency Type(0～F)	PriceElement(HEX)
2	PriceElement(HEX)	PriceElement(HEX)
			3	PriceElement(HEX)	PriceElement(HEX)
4	PriceElement(HEX)	PriceElement(HEX)

The modification can be performed in various ways, and the above is only an example of the modification, but not limited to the above modification.

For the WIN MAP specification, the method can be realized by modifying the Price sub-parameter of script restriction, the principle of which is the same as the realization mode of CAP protocol, and the description is not repeated.

Example three: existing parameters are newly added or modified to include currency type information.

For example, the PA, PC, etc. have a very large number of operating parameters, and many parameters are composite parameter types, so that a currency type parameter can be added to other parameters of PA, PC, and the added parameter can be different from the first example, for example, a currency type parameter parallel to variable parts is added to the parameter of the existing variable information (variable message); or, the structure of a certain existing parameter may be modified, similar to the structure of the price in the second example, for example, the existing basic information identifier (elementary identity id) in PA or PC may be modified, so that the basic information identifier carries the currency type. Thus, the new addition or modification of the existing parameters and the existing amount parameters contain currency type information and amount information, respectively.

In short, in the first embodiment, the money type information and the amount information may be included in the playback operation instruction, and the present application is not limited to how the money type information and the amount information are set in the playback operation instruction.

Referring to fig. 1a, a schematic flow chart of playing an amount prompt tone including a currency type based on an INCP or CAP protocol according to an embodiment of the present invention is shown. In the embodiment shown in the figure, the SCP instructs the IP to perform PA and PC operations, and the intelligent device is an independent IP.

101-104, an initializing connection is established between an SCP and an SSP, the SSP sends an initializing DP (initialDP) to the SCP, the SCP sends a request for reporting a BCSM event (RequestReportBCSMEvent) request and a request for establishing a temporary connection (instableTechmethodConnection) to the SSP, the SSP establishes a temporary connection with an IP according to the received request, and then the IP sends an auxiliary request instruction (asisRequestInstruction) to the SCP to request the SCP to send a voice operation instruction. All the steps are completely the same as the existing processing mode.

And 105-106, the SCP sends a voice operation instruction for playing a voice prompt (PlayAnnotice) and a voice prompt and collecting user information (PromptAcllectUserInformation) to the IP, wherein the two instructions both comprise currency type information and amount information.

Step 107, the IP extracts the money type information and the amount information from the received instruction, performs voice synthesis, and plays an amount prompt tone including the money type.

Step 108, the IP returns a voice prompt to the SCP and collects a user information Result (promptAndCollectitUserInformation Result).

In step 109, after receiving the information returned by the IP, the SCP sends a disconnect forward connection (disconnect forward connection) to the SSP to disconnect the connection with the IP.

Thus, playing of the money amount prompt tone including the currency type is realized.

Referring to fig. 1b, a schematic flow chart of playing an amount prompt tone containing a currency type based on an INCP or CAP protocol according to another embodiment of the present invention is shown. The difference from the embodiment shown in fig. 1a is: the IP in FIG. 1b is set within the SSP, while the IP in FIG. 1a is a stand-alone IP. Based on this, the procedure for the SCP to establish a connection with the IP is different, i.e. steps 103 and 104 in fig. 1a correspond to step 103 in fig. 1 b. The rest is exactly the same as that shown in fig. 1.

The process of establishing connection between SCP and independent IP and the process of establishing connection between SCP and integrated SSP/IP are completely prior art, are not the focus of the present invention, and will not be described in detail. The present invention focuses on enabling the IP to play a monetary prompt containing a currency type, independent of whether the IP is integrated in the SSP.

Referring to fig. 2, it is a schematic flow chart of playing an amount prompt tone containing a currency type based on the WIN MAP protocol according to a first embodiment of the present invention.

Step 201-205, SSP sends ORREQ (originationRequest) message to SCP, SCP sends SEIZEES (SeizeResource) message to SSP, SSP returns response seizers to SCP; SCP sends CONNRES (ConnectResource) message to SSP, SSP establishes temporary connection with IP according to received request, and IP sends INSERQ (Instructionrequest) message to SCP. All the steps are completely the same as the existing processing mode.

In step 206, the SCP sends an srfdir (srfdirective) message to the IP, where the message includes currency type information and amount information.

Step 207, the IP extracts the currency type information and the amount information from the received instruction, carries out voice synthesis and plays the amount prompt tone containing the currency type.

In step 208, the IP returns a response srfdir to the SCP.

And 209-210, the SCP returns a response instreq to the IP and returns a response orreq to the SSP.

The IP in the embodiment shown in fig. 2 is also independent, and in practical applications, the IP can be integrated in SSP.

The second embodiment: setting a corresponding relation between the currency type and the voice number in the intelligent peripheral IP, receiving a playback operation instruction from a service control point SCP by the intelligent peripheral IP, extracting a money parameter and the voice number from the playback operation instruction, extracting the currency type corresponding to the voice number according to the corresponding relation, carrying out voice synthesis on the currency type and the money, and playing a money prompt tone containing the currency type.

Similarly, the IP in the second embodiment may be a standalone IP or may be integrated in the SSP.

The playback operation instruction from the SCP can be based on INAP protocol, and also can be based on CAP protocol or WIN MAP protocol. According to actual needs, playback operation instruction packets PA, PC or PR based on INAP protocol or CAP protocol, or any combination of the three.

As can be seen, the difference between the second embodiment and the first embodiment is that: in the first embodiment, the currency type information is issued to the IP through the playback operation instruction, and the IP directly acquires the currency type information and the amount information according to the received information; in the second embodiment, the money type information is set in the IP, and the money type information is associated with the voice number, so that, when the IP receives the playback instruction information, the voice number is extracted from the received message, and the money type information is obtained based on the association relationship set locally.

Aiming at the first implementation mode, the embodiment of the invention also provides a voice playing system supporting multi-currency, which at least comprises an SCP, an SSP and an IP, wherein the SCP establishes a connection relationship with the IP through the SSP,

SCP is used for IP to issue playback operation instruction, which contains currency type information and amount information; the playback operation instruction sent by the SCP can be based on INAP protocol or CAP protocol, and can also be based on WIN MAP protocol.

And the IP is used for extracting the currency type information and the amount information according to the received playback operation instruction, carrying out voice synthesis and playing the amount prompt tone containing the currency type.
